Personal trainers: run small group sessions online

Small group training lets you coach four to eight people in the hour you'd give one client, at a lower price for each. It only works when the group is the right size: enough to fill the session, few enough to coach everyone. With Book, each group is a service with a set number of places; clients book their own place, and a full session leaves your page.

On Book, each service has a name, a price and an optional description, all shown on your public page. Each slot belongs to one service, sits within one day and has its own capacity.

Durations, places and prices are examples: set your own.

Set places to the number you can coach well with your equipment. Each online booking takes one place, and when the last place goes, the session leaves your page. A friend who wants to join books their own place.

Slots repeat weekly on the weekdays you choose until an end date. Run groups in blocks, such as six weeks of Tuesday and Thursday evenings, so members commit and progress together. Clients book each session, or you book a whole block for someone from your bookings list.

Say in the description where to meet, what to wear and what happens in bad weather. If you cancel, tell each participant yourself; Book doesn't email clients about changes. The booking form takes phone and email, so you can reach everyone.

Two friends training together can each book one of two places. If one wants to book for both, create a pair service with one place and a price for two.

Slots of different services can overlap, so keep one-to-ones at times when no group runs, or close the one-to-one slot once a group starts filling. Your bookings sync with Google, iPhone or Mac calendars.

The booking form takes first name, last name, email and phone, plus an optional note that reaches you in the new booking email. Ask for experience level. Tell clients with injuries or health conditions to contact you before booking, rather than writing details in the note, which appears in their calendar file.

Book doesn't take payments, sell memberships or class packs, or send reminders. Clients can't move or cancel online: they contact you. One booking page per business, no staff field: with other coaches, create groups per coach. Book costs €5/month, everything included: unlimited services and bookings, no commission, no contract.
